Answer:
b) Explain how the hybridization of atomic orbitals leads to the formation of sigma and pi bonds. Answer: Hybridization of atomic orbitals results in the formation of sigma bonds through end-to-end overlap of hybrid orbitals. Pi bonds are formed through side-by-side overlap of unhybridized p orbitals.
